Hill family and Kunderman family

I am searching for information on Jakob Hill, born about 1842 in Russia and his wife Maria born about 1846 in Russia. Jakob Hill immigrated to Canada in 1842 and later this family came to USA

His children which I know of are Jakob, Johannes, Christian, Maria, Emilie, Katarena, Dorothea all born in Russia.

His son Johannes Hill married Lena Carolina Kunderman who was born 1885 in Austria.Her parents were Mathias (Matthew) Kunderman born 1849 in Austria and Margaretha Loui, born 1856 in Austria. The Kunderman family arrived in New York and then went to Canada.
